Actually, at least for TCP and well-behaved UDP applications, that's
not so. Dropped packets are interpreted by the sender as an indication
of congestion, which will cause it to slow down. Another strategy (I
suspect, though I haven't tried it) is to delay ACKs, since the sending
TCP will use the ACk arrival rate to clock the sending rate.
